Aluminum Low-Pressure Barbed Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water
- Temperature Range: -40° to 230° F
- Tubing: Use with hard (Durometer 75A-60D) EVA plastic, polyethylene plastic, polyurethane rubber or PVDF plastic
Made of aluminum, these fittings are lighter in weight than other metal barbed tube fittings and have good corrosion resistance. The barb grips onto tubing, providing a secure hold with no clamp required.

Nickel-Plated Brass Push-to-Connect Tube Fittings for Air
- For Use With: Air, Lubricated Air
- Temperature Range: 0° to 140° F, except plugs and straight connectors are 32° to 140° F
- Tubing: Fittings with Release Ring and Fittings with no Release Type: Use with firm or hard (Durometer 95A-60D) nylon plastic, polyethylene plastic or polyurethane rubber
Fittings with Release Sleeve: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber
Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring or sleeve and pull the tubing out of the fitting.
Fittings with release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.

Moisture-Resistant Push-to-Connect Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water,
except Manifolds with Swivel: Air, Water - Temperature Range: 32° to 100° F
- Tubing: Use with firm (Durometer 90A-95A) nylon plastic or polyurethane rubber
These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting. They have good corrosion resistance.

Brass Compression Tube Fittings for Air and Water
- For Use With: Air, Lubricated Air, Water
- Temperature Range: See table
- Tubing: Use with firm or hard (Durometer 1A-95A or Rockwell 15T 1-15T 60) nylon plastic, polyethylene plastic, polypropylene plastic or polyurethane rubber
- Specifications Met: SAE J512, except metric sizes
A single sleeve (ferrule) compresses the tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included. Fittings are also known as flareless fittings. They are brass for good corrosion resistance.
Tube supports (sold separately) are recommended if you want to use the fittings with soft polypropylene and polyethylene tubing to prevent the tube from collapsing.
Install plugs with a nut (sold separately) on the end of fittings to block the flow of air or water.

Plastic Compression Tube Fittings for Air
- For Use With: Air, Lubricated Air
- Temperature Range: -30° to 210° F
- Tubing: Use with firm or hard nylon plastic, polyethylene plastic or polypropylene plastic
Lighter in weight than their metal counterparts, these compression fittings are polypropylene. They have excellent impact and abrasion resistance. Fittings include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly. The sleeve compresses the tubing as you tighten the nut, creating a strong seal. Fittings are also known as flareless fittings.
Tube supports (sold separately) are recommended if you want to use the fittings with soft nylon, polypropylene, and polyethylene tubing to prevent the tube from collapsing.

Stainless Steel Push-to-Connect Tube Fittings for Chemicals
- For Use With: Alcohol, Bleach, Lubricated Air, Nitric Acid, Sodium Carbonate, Sulfuric Acid
- Temperature Range: 0° to 175° F
- Tubing: Use with firm or hard (Durometer 80A-60D) FEP, polyethylene, or PTFE plastic
Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Instead of a release ring, these fittings have a release sleeve that slides back to disconnect tubing.
